expand-3(x+3y=8)

Solution

expand

- 3 (x + 3 y = 8)

Solution

- 3 x - 9 y = 8

Solution steps

- 3 (x + 3 y = 8)

= - 3 (x + 3 \cdot 8 = y)

Apply the distributive law:

a (b + c) = ab + a c

a = - 3, b = x, c = 3 y = 8

- 3 x + (- 3) \cdot 3 y = 8

Apply minus-plus rules

+ (- a) = - a

- 3 x - 3 \cdot 3 y = 8

Expand

- 3 x - 3 \cdot 3 y : - 3 x - 9 y

- 3 x - 9 y = 8
